In order to view these stereographs in 3D, try the following: Look at the 2 white dots and let your eyes go ‘woozy’ until you are able to see 3 white dots. Gradually focus on the middle dot of the 3 and when you have it firmly in focus, gently lower your gaze to see the stereo effect. Some people are able to do this straight away and for others it may take quite some time to achieve – simply persevere – most people will be able to do it ultimately with a little practice.
